Question 567 Rules of the Road

The correct answer is C) Intermittent flashing amber beacon for submarines. This is authorized by the Secretary of the Navy as an additional navigational light for a ship of war, specifically for submarines. The intermittent flashing amber beacon helps identify the submarine's presence and location to other vessels, enhancing maritime safety. The other options are incorrect because they do not represent authorized additional navigational lights for ships of war. Option A describes lights for mine-clearing operations, option B describes signals for torpedo firing exercises, and option D describes lights for aircraft carrier operations, none of which are the same as the intermittent flashing amber beacon for submarines.
